The U.S. Air National Guard is a reserve component of the United States Air Force that provides support for both state and federal missions. It consists of airmen who serve part-time while also pursuing civilian careers or education. Members can be called to active duty during emergencies, natural disasters, or military operations. Each state, territory, and the District of Columbia has its own Air National Guard units, which can be mobilized to assist in local emergencies or deployed overseas. The Air National Guard plays a crucial role in national defense and disaster response, ensuring readiness and support for various missions.
